after a decade of leading the big apple in the 1980's, he's also remembered for saving the city from near financial ruin. koch died today at the age of 88 from heart failure. he was famous for asking, how am i doing? a brief time ago i asked the new yorkers' john cassidy for his verlander. >> he was great new yorker. when the city was sort of down in the dumps and people thought this was going bankrupt he came up from the streets and said, we're not finished. i can run this place. he put more cops on the street, he stood up to the unions during a big transit strike, he attracted more investment. lots of people didn't like him but they sorted respected his energy and that he wasn't giving up on the city. >> i mean, his supporters say that ed koch changed the narrative of new york from one of decline to one of resurgence. sounds like you think that might be true? >> well, i mean, that's a bit too much. you can't put it all down to him. but he sort of got the ball rolling. he came in as mayor in 1977 and just joined the campaign then.
